The effects of iodinated contrast media exposure on thyroid functions after angiography in patients with subclinical hyperthyroidism: a retrospective study

In patients with subclinical hyperthyroidism, thyroid function mostly remained stable or became euthyroid after ICM exposure. However, a group of patients developed clinical hypothyroidism or hyperthyroidism. These results suggest that patients with subclinical hyperthyroidism should be closely monitored when using ICM. Long-term follow-up will contribute to a better understanding of the possible risks in this patient group.
